Research interests:
The interest underlying Dr. Keller's research is understanding the relationships between physical processes and biogeochemical environments in vadose (unsaturated) zones. The occurrence and rates of many geologic processes -- carbon cycling, weathering, contaminant attenuation, microbial respiration -- depend on these relationships. His work aims to test our presently vague ideas about these dependencies, and develop practical predictive relationships emphasizing the control exerted by geologic settings. An equally compelling line of his research is aimed at understanding the sustainability of the groundwater resource here on the Palouse of southeast Washington. Research in this area (collaborative with R. Allen-King) involves isotope-geochemical constraints on groundwater ages and recharge rates, and assessment of occurrence and fate of agricultural chemicals (applied to more than 90% of the land area).
